Petechiae/Purpura in Well-Appearing Infants
Pediatric Emergency Care, 06/20/2012
Lee MH et al. – Well infants with localized purpura and/or petechiae with an absence of fever are more likely to have a benign etiology. Further study is required to determine if a full blood count and coagulation profile is necessary, or a period of observation (4hours) is all that is required. If there is no progression of signs, it is likely that they can be safely discharged. The likely cause may be due to a tourniquet phenomenon (eg, diaper).
